43 Claims.

This invention relates to machines for use in the manufacture of shoes and more particularly to machines for making stitchdown shoes, and is illustrated herein as embodied in a machine for pulling over the uppers of stitchdown shoes.

In the manufacture of shoes of the type referred to, the lower portion of the upper is turned outwardly away from the last upon Which the shoe is to be made to provide an outturned margin or flange, and the upper is permanently attached to a mid-sole or other sole member on the last by securing this outturned margin to the portion of the sole member which projects beyond the periphery of the last bottom, the attaching means usually consisting of fastenings, such as stitches, located close to the last in the angle or crease formed by the side port on of the last and the outwardly extending margin of the upper.

Before the upper and sole member can be properly attached to each other by the lasting stitches, however, they should be assembled in proper relation on the last and the upper should be pulled over and secured in a suitable manner to the projecting sole member in order th t the upper may be held in pulled-over position on the last until the permanent attaching means can be inserted.

Machines for pulling over stitchdo-wn shoes or machines provided with special apparatus or attachments for performing this operation are not usually arrranged also to secure the upper in pulled-over position on the last by inserting fastenings such as staples or the like, and those which are so arranged usually involve departures from the more common methods of making stitchdown shoes followed or employed by most manufacturers. Consequently, it has been customary heretofore in many factories for the operators to perform this relatively important operation by hand with hand or bench pincers or grippers and with the aid of a machine arranged to insert single fastenings, such as staples. through the upper and sole member. In carrying out the pulling-over operation by this process, the operator assembles an upper and a sole member on a last in the usual manner and uses the hand or bench grippers to pull over the upper at one side of the shoe and he inserts a fastening or staple through the upper and sole member on that side after it has been pulled over. He then pulls over the other side of the upper with the hand grippers and inserts a fastening in that side also.

It will be apparent that the above procedure is apt to be unsatisfactory today, when speed, economy and good workmanship are essential, because in many instances shoes pulled over by this method are not pulled over uniformly 01' evenly on both sides and, consequently, the uppers are frequently displaced widthwise of the last which results in poorly constructed or defestive shoes. Moreover, the uppers are not always pulled over the last as tightly as they should be, especially at the forepart, when the upper has been pulled over one side at a time by this hand method. In addition, the hand method obviously involves more time and labor than would be required in performing the same operation, including the insertion of fastenings, by machine.

An object of the present invention is to provide an improved machine for use in the manufacture of shoes which is adapted to perform a pulling-over operation on shoes, such as stitchd-own shoes, the machine being particularly arranged to perform this operation efiiciently, rapidly and with better and more uniform results than have been possible heretofore by the methods referred to.

To this end the invention provides, in accordance with one feature. an improved machine provided with a support for receiving a last, the last having an upper mounted thereon together with a sole member which projects beyond the last bottom, the machine being prov ded with further means or mechanisms at opposite sides of the su ort for ri ing the opp t mar ns o the upper at the forepart of the last and holding these margins in an outturned position over the projecting sole member. Further means is also provided on the machine for effecting relative movement of the shoe support and the gripping mechanisms heightwise of the last to cause the upper to be pulled over the last and, in accordance with another feature of the invent on, mechanisms are provided for inserting metal fastenings, such as staples. through the projecting sole member and upper margins at opposite sides of the last to secure the upper in pulled-over position on the last.

As illustrated herein, the shoe support is arranged to move heightwise and lengthwise relatively to the gripping mechanisms in order to accomplish the pulling-over operation, the grippers remaining stationary during this movement so that the upper at opposite sides of the last will, in efiect, be pulled downwardly and forwardly of the last by such movement. At the termination of the relative movement, the grippers are arranged to hold the opposite margins of the upper in an outturned position overlying the projecting margin of the sole member. In the present embodiment of the invention, as illustrated herein, the fastenings may comprise ordinary preformed staples supplied, for example, from a usual staple strip or bar and, in accordance with a further feature of the invention, the fastening inserting mechanisms are arranged to insert the staples upwardly in an inverted position so that they will pass first through the projecting sole member and then through the overlying margins of the upper, the staples being thereafter clinched by the mechanisms against the exposed surface of the upper. As illustrated, the staples are inserted simultaneously at the opposite sides of the last and are preferably located by the inserting means at predetermined distances from the last bottom in the angle or crease formed by the last and the outturned margins of the upper.

In order to insure that the stitchdown upper will be pulled over the last smoothly and tightly at all portions thereof, the machine is also arranged to cause the opposite side portions of the upper to be moved inwardly toward the support at a predetermined time in the cycle of operations of the machine to press the upper against the sides of the last, this movement taking place after the pulling-over operation has been performed but before the fastenings have been inserted. As herein illustrated, the pressing op-- eration is performed automatically by the machine by causing the opposite margins of the upper and the projecting sole member to be first clamped between the fastening inserting mechanisms and stationary members or anvils provided for clinching the staples. the opposite sets of mechanisms being thereafter caused to move inwardly toward the support with a yielding action while remaining in clamping engagement with the upper and sole member. In this way, the upper is pulled over the last tightly and evenly and the fastenings are inserted while the upper is held in such position, the position of the fastenings, as indicated above, being determined or controlled by the fasienins inserting mechanisms.

In addition to the foregoing, the present invention provides various other novel features and arrangements of parts among which are improved means for adjusting the gripping and fastening inserting widthwise and angularly with respect to the support to adapt them for operating upon shoes of different styles and sizes, the widthwise adjusting means, as herein illustrated, comprising a single member in the form of a manually operated screw for adjusting the mechanisms at both sides of the support simultaneously toward or away from the support. The means for obtaining an angular adjustment of the mechanisms are separate or individual for each set of mechanism so that they may be adjusted independently of each other into different angular positions with respect to the support in accordance with the size or style of the shoe being operated upon. As herein illustrated, the single means for initially adjusting the gripping and fastening inserting mechanisms toward or away from the support is arranged so that, while it accomplishes the same functions as the means forautomatically moving these mechanisms in wardly to press the upper yieldingly against the last, it does not interfere with the operation of this automatic means but, on the contrary, assists said means in producing this inward movement of the mechanisms, the automatic means, however, operating independently of the operation of the single adjusting means.

With the above and 0t .er objects and features in View, including means for releasing the grippers after the upper has been clamped but before it is pressed against the last, and improved means for actuating the different operating mechanisms of the machine in proper timed relation to each other, the invention will now be described in detail in connection with the accompanying drawings and will thereafter be pointed out in the claims.

The illustrated machine is provided with an upstanding base or frame 2i] supported on four legs and extending upwardly a. convenient distance for an operator to present the Work to the machine. The upper end of the base 20 is substantially rectangular in plan View and has short vertical studs 22 secured to it by screws adjacent to its four corners, these studs supporting on their upper ends a horizontal plate or table 2:3 which carries the operating mechanisms of the machine. The plate 24, as illustrated in Figs. 1 to 3, inclusive, is much longer than it is wide and is positioned with its lengthwise dimension extending forwardly and rearwardly of the machine.

On the forward portion of the tab-1e 24 are mounted two upstanding U-shaped brackets 26, 28 (Figs. 2 and 3) secured to the table byscrews 38. Pivoted between the ears of the bracket 26 on a pin 32 is a lever 34 which forms the forward link of a toggle, the other link of which is provided by a second lever 36 pivotally mounted on a pin 38 between the ears of the other U- shaped bracket 23. The toggle levers 36, 38 are pivotally connected to each other by a pin til extending through slots formed in the adjacent ends of said levers, the toggle lever at being bifurcated at its inner'end to straddle the lever 36. The pin 49 is secured in the upper end of a treadle rod 32 which passes downwardly through a hole in the table and; at its lower end (Fig. 1), is pivotally connected to a foot treadle dll fulcrumed between fixed collars it on a long horizontal shaft 46 extending widthwise of the machine and rotatably mounted in bearings formed on the lower ends of the two rearward legs of the base 20, the treadle id being normally maintained in its elevated position by a tension spring '38 extending between the treadle and a fixed upper portion of the base or frame.

Pivotally mounted on a pin $9 on the forward end of the toggle lever 35 is an upwardly extending arm 50 and pivotally mounted on a pin on the rearward end of the other toggle lever 36 is a similar arm 52, these two arms, as shown in Fig. 2, being parallel and having their upper ends bifurcated to provide ears between which is pivotally mounted, by means of pins at and lit, a long narrow T-shaped plate 53, the upper surface of which is maintained in a horizontal position by reason of the parallel arms 56, 52, the plate 58 constituting the shoe supporting member of the machine. A heel block 66 is removably secured on the forward portion of the shoe support lit by a pair of pins t2 projecting from. the lower surface of the block and arranged to enter any of a plurality of sets of holes 6d spaced from each other lengthwise of the support, thereby permitting the heel block to be readily removed and adjusted lengthwise of the support to accommodate shoes of different lengths or sizes.

The inner or rearward portion of the support 53 has secured thereon a pair of small rectangular blocks 66, 68 (Figs. 2 and 8) which serve as toe rests for supporting the toe end of the shoe, the blocks 66, fill being located in substantial alinement with the opposite edges of the plate by dowel pins and being secured respectively thereto by screws '58 Mounted on the inner end of the support 53 is a toe gage "M which is secured to a rectangular block it on the support by a pair of screws it, the gage being adjustable lengthwise of the support to adapt it for shoes of different sizes by means of a horizontal adjusting screw til threaded into the block l8 and provided with a knurled head 82. At its rear end the toe-gage M has a downwardly extending ear 8d which is bifurcated to engage a circumferential slot in the screw as so that, when the clamping screws '58 are loosened and the adjusting screw is rotated, the gage may be adjusted into the desired position lengthwise of the shoe support 53, the clamping screws it. as shown in Fig. 8, passing through elongated slots 86 in the gage to permit the adjustment to be made.

The forward portion of the toe gage M (Figs. 2 and 8) extends over the toe rests til, 68 in position to engage the toe end of the last in the ace while permitting the projecting portion of the sole to pass under the gage and permitting the marginal portions of the upper to extend over the gage and toe rests. As illustrated in Figs. 2, 8 and 9, the forward or operative end of the toe gage comprises a relatively wide vertical surface 88 extending transversely of the support 58. Fig. 8 shows a shoe mounted on the shoe support with its heel end resting on the heel block 60 and its too end engaging the toe rests 66, 68, this figure illustrating also how the toe gage is locates the last lengthwise of the support in position for the shoe to be operated upon by the operating instrumentalities of the machine.

The inner toggle lever 36 (Fig. 2) has an arm to projecting upwardly above its pivot 38 and pivotally connected to this arm by a pin 92 are a pair of long links 94 which extend forwardly and are pivotally connected at their front ends to the upstanding arm 58 by a pin 95 arranged to be inserted in any one of a series of holes 98 formed heightwise in the arm 59 so that the front ends of the links 9 3 may be adjusted heightwise of the arm. The forward toggle lever M has a pair of adjustable stop screws iilil and H32 threaded thereon at opposite sides of its pivot 32, the screw iilli determining the broken or inoperative position of the toggle by engagement with the plate 2d, as shown in Fig. 2, and the rearward screw :62 determining the straightened or operative position of the toggle. The extent of operative movement of the toggle levers about their pivots, therefore, may be varied by adjustment of the stop screws in the lever 3d.

Depression of the treadle 34 moves the rod d2 downwardly to straighten the toggle levers 34, 3G and to swing the opposite ends of these levers upwardly, thereby moving the parallel arms 59, 52 upwardly to elevate the shoe support or plate 53. The links 8 are moved forwardly, or toward the left in 2, during this action by the arm so that, as the parallel arms 55, 52 move upwardly, they are caused to swing forwardly about their pivots a distance depending upon the adjusted position of the links 94 on the forward arm 59. Consequently, a shoe mounted on the support 58 will, upon depression of the treadle M, be moved upwardly with the support simultaneously in a heelward direction as the support is moved forwardly toward the operator a predetermined. distance relatively to the rest of the mechanism of the machine.

In order to maintain the treadle 4- 3 depressed after it has been operated, a pair of latches Hi l, we are provided at the front end of the table 2%, these latches being pivote on a horizontal pin 88B mounted in a forwardly extending projection on the table. Springs 5 i8 and H2 (Figs. 2 and 3) are connected to the latches and to pins lid, H6 in the U-shaped bracket 28 and tend normally to swing the latches rearwardly, as viewed in Fig. 2,. against the lower pivot pin 49 for the arm When the pin it is elevated, through depression of the treadle, the latches drop under the pin and lock the mechanism in its operated position with the support 58 in its elevated and forward position.

If it is desired to inspect the shoe before the treadle has been completely depressed, for example, to insure that the shoe has not been displaced on the support, one of the latches may have its notched portion located slightly below that of the other latch which will permit the operator to release the treadle to inspect the work after the lower latch has moved under the pin 49 without causing the mechanism to return to its open or inoperative position. As illustrated in Fig. 2, the latch E68 is slightly lower than the latch iii-ii. he latches H34, I56 are provided respectively with handles II 8, I29 whereby they may be released manually to return the shoe support to its lower position when the operation has been completed or, if desired, to return the support if the shoe has become displaced before the treadle has been fully depressed.

The action of the treadle mechanism in elevating the shoe support 58 and simultaneously moving it forwardly toward the operator, as described above, is utilized in the machine for performing a pulling-over operation on the upper of a stitchdown shoe, this action taking place relatively to further mechanism of the machine, part of which is adapted to grip and hold the upper at opposite sides of the forepart of the shoe and thereby to cause the upper, in effect, to be pulled downwardly and forwardly over the last through the movement of the shoe support 58 relativelyto said further mechanism. The gripping mechanism referred to is best shown in Figs. 1, 2 and 8 to 10, inclusive, and since this mechanism is practically identical at opposite sides of the support, only the mechanism at the right-hand side of the machine, as viewed in Fig. 1, need be described in detail herein.

The gripping mechanism is arranged to engage the upper a short distance rearwardly of the tip line of the shoe and comprises an upper gripper I22 of substantial width pivoted on a pin I24 mounted between side walls projecting inwardly from a carrier member I26 which, in turn, is secured by pins or screws I28 to a thick plate fastened to a'vertical supporting plate I30, the latter plate being arranged for angular adjustment relatively to the shoe support 58, as will be later explained. The upper gripper I22 is provided on its inner end with a slot or groove I 3I with which a lower gripper of the mechanism cooperates to grip the shoe upper in a yielding manner which permits the upper to slip under excessive tension, as will be pointed out, the grip per I22 being arranged to yield upwardly about its pivot I24 under sufiicient pressure by reason of a relatively heavy compression spring I32 (Fig. 1) mounted in a cylindrical opening formed in the carrier member I28 and normally pressing upwardly against an enlarged lower end on an adjusting screw I3 I threaded through an outwardly extending arm I36 of the gripper I22. A threaded collar I38 is provided for locking the screw I34 against movement in the arm I35 after the screw has been adjusted to produce the required tension of the spring I32. The spring urges the outer arm I36 of the gripper I22 upwardly about its pivot Ifid and normally maintains the gripper in a stationary operative position which is determined by an upstanding projection or lug Hill on the gripper engaging a fixed stud I42 extending between the opposite side walls of the carrier I28.

The lower jaw of the gripping mechanism comprises a substantially L-shaped gripper I having a single transverse rib or tooth I56 on its lower arm for cooperating with the groove I3I in the gripper I 22, and provided on its upper arm with a pair of upwardly extending ears I48 (Figs. 2 and 9) which straddle the upper gripper and are pivotally mounted on fixed pins I59 secured by set screws in the opposite side Walls of the carrier member I26. The gripper I44 is slotted at its outer portion to receive the inner end of a toggle link I 52 pivotally connected to the gripper by a pin I55. The other end of the link I52 is connected to an outer toggle link or lever I56 by a pin I58 (Fig. 1), the link I56 being longer than the link I52 and being pivoted about midway of its length by a pin I Bil to ears depending from the carrier member I26. The outer end of the toggle lever I56 is pivotally connected by a pin I62 to a treadle rod I64 which extends downwardly and is yieldingly connected at its lower portion to a treadle lever I56 mounted on the shaft 46 and rigidly secured to said shaft by a pin I68 so that movement of the treadle I66 rotates the shaft in its bearings on the machine.

The yielding connection between the treadle rod I64 and the treadle I66 is provided, as herein illustrated, by a vertical plate I ll! rigidly secured to the treadle lever and carrying at its upper portion a block I I2 rotatably mounted in the plate by a pin. The treadle rod passes through a hole in the block In and has a compression spring I'III surrounding it below the block, the spring being adjustably retained on the rod by a lock nut I16. Above the block I72, the treadle rod has secured to it by a set screw a collar I13 which is normally urged downwardly against the block by the spring I'M to locate the treadle rod in a predetermined elevated or inoperative position, as shown in Fig. 1. A tension spring I80, extending between the treadle and a fixed portion of the frame, maintains the treadle normally in its elevated position which is determined by its engagement with an adjustable stop screw I82 threaded through a horizontal arm I84 rigidly secured to the frame. When the treadle I66 is depressed to operate the grippers through the toggle mechanism described above, the treadle rod I64 will be lowered yieldingly through the action of the spring II I which will be compressed between the block I72 and the lock nut I15. When the treadle is released and is elevated by the spring IBIJ, it raises the treadle rod positively to inoperative position by the engagement of the block I'l2 with the fixed collar I'I8. the spring I14 expanding to maintain the collar against the block.

As pointed out above, the shaft 45, upon which both treadles-are mounted, is rotated when the gripper treadle Ififi is depressed because the latter is pinned to this shaft. The shaft 45 extends across the entire machine and has mounted on its opposite end, as viewed in Fig. l, a forwardly extending lever I85 pinned to the shaft like the treadle I66 and provided with a rotatable block I88 through which a vertical rod I93 passes, a spring I92 being provided on the rod below the block I88 to urge the rod downwardly and maintain a fixed collar I94 normally against the block. The upper end of the rod I99 is pivotally connected by the pin I62 to the toggle mechanism for operating the lower gripper jaw I44 of the left-hand gripping mechanism which, as previously explained, is substantially the same as the gripping mechanism described above except that it is located in an opposite or reverse position.

Depression of the gripper treadle I66, therefore, straightens the toggles I52, I56 on both sets of gripping mechanisms and swings the lower grippers EM upwardly about their pivots I5t into gripping relation with the normally stationary upper grippers I22, the latter, however, as pointed out above, being arranged to yield under sufiicient pressure to compensate for differences in the thicknesses of the upper materials of the shoes operated upon.

In mounting a stitchdown shoe on the support 58 prior to the operation of the grippers, the

.pass.

upper is first mounted on the last and the sole member is secured temporarily to the last bottom in any usual manner as, for example, by a few tacks inserted along the central portion of the sole. The heel end of the shoe is placed on the heel block 60, which will have been adjusted into the proper lengthwise position for the shoe being operated upon, and the forepart of the shoe will rest on the fixed toe rests or abutments 65, 88. The toe end of the last will be moved into engagement with the toe gage M which, if necessary, will have been adjusted longitudinally as much as required for locating the shoe in a proper position lengthwise of the support.

It is desirable to position the shoe widthwise as well as lengthwise on the support 58 and, accord ingly, the machine is provided with a pair of side gages arranged to engage the opposite edge faces of the sole member adjacent to its toe end and to position the forepart of the shoe laterally or widthwise of the support so that it will be located substantially central with respect to the opposite gripping mechanisms which are located somewhat rearwardly of the tip line of the shoe.

These side gages, as iliustrated in Figs. 1, 8 and 9, comprise a pair of l ng plates'or blades 18! secured by screws 983 in horizontal slots 585 formed in the forward surfaces of the supporting plates E33, the gage having their inner ends rounded over for engaging the opposite edges of the sole member adjacent to its toe end and being adjustable in the slots widthwise of the shoe by means of horizontal slots iii! in the supporting plates it!) through which the screws E83 18! are located a short distance above the top surfaces of the toe rests 55, 58 so that they will be in position to engage the opposite edge faces of the sole member mounted on the toe rests. When the support 58 moves upwardly, as indicated diagrammatically in Fig. 9, the sole is moved out of engagement with the side gages which are stationary-on the plates its.

After a stitchdown shoe with its sole member secured to the last bottom hasbeen mounted on the support 53 and has been correctly positioned lengthwise by the toe gage M and widthwise by the side gages lSl, the forepart of the upper extends outwardly away from the last-at each side of the shoe and is in position to be engaged and held by the grippers, as illustrated in Figs. 8 to 19, inclusive. The operator hen depresses the treadle I65 to operate the gripping mechanisms:

After the grippers at both sides of the shoe have-gripped the upper, it is desired tomaintain them in gripping relation with the upper without holding the treadle H53 depressed, so that the operator will be free to perform other functions in operating the machine. To this end, the lefthand supporting plate I59, as viewed in Fig. 1, has a horizontal pin 185 rotatabiymounted therein upon the forward end of which is secured a latch I98 which extends downwardly and is pro-- vided with anotch or shoulder 2st] at its lower end, the latch-having a split hub surrounding thepin I95 and being rigidly secured thereto by a clam-ping screw 2&2.

On the inner end of the pin 2%, behind the plate I39, is securedbya tapered pin 2% a later: ally extending member 2% provided with an inner arm 20''! and a lower arm 2% to which is secured a tension spring 2S9, the other end of th spring being secured to apin' 2H fastened in the plate I 30. The spring 2M3 tends normal-ly'to urge the member 2% in a clockwise direction, asseen in As shown in Figs. 8 and 9, the side gages Fig. 1, to hold the inner arm 20'! against a stop pin 2% mounted in the plate I39, thus holdin the latch I98 in a vertical position adjacent to the pin E62 which connects the toggle lever I56 to the vertical rod I98 of the left-hand gripping mechanism. When the treadle I66 is depressed to straighten the toggles H52, i515 at the opposite sides of the machine and thereby to close the grippers, the pin H52 is moved downwardly and swings the latch to the right until the pin is below the shoulder 296, at which point the latch snaps over the pin to prevent it from moving upwardly again until the latch is released, thereby locking the grippers in their operated position and holding the treadle I66 depressed. An upwardly extending arm 2 i 2 is provided on the latch for releasing it manually, if desired, and further connections are provided between the member 205 and other mechanisms of the machine for releasing the latch automatically during the operation thereof, these connections being more fully described hereinafter.

In the normal operation of the mechanism thus far described, the operator, after mounting a shoe on the support 58, depresses the treadle 666 to operates the grippers simultaneously at both sides of the support, thereby gripping the opposite sides of the upper somewhat rearwardly of the tip line, as shown in Fig. 9. He then depresses the central treadle 44 to effect the pulling-over operation on the shoe, as described above, through the upward and forward movement of the shoe support 58 relatively to the grippers, the operator holding the shoe in position on the support during this relative movement to prevent it from becoming displaced on the support.

Before describing these operations in further detail, however. or describing the fastening inserting operation which follows them, it should be explained that, before the grippers are operated, they and other mechanisms associated with them, including the fastening inserting mechanism above referred to, have to be adjusted sometimes with respect to the shoe support 58 in order to accommodate or adapt the mechanisms for operating upon shoes of different shapes and sizes. Accordingly, the machine is provided with mechanism for adjusting the grippers and associated mechanisms at opposite sides of the support 58 into different positions relatively to the support and to the shoe mounted thereon, so

that the grippers and fastening inserting mechanism will be located in the proper widthwise positions and at the proper angles for operating upon a shoe of the particular size and shape of that on the support. 7

Since the adjusting mechanism referred to moves the opposite fastening inserting mechanisms of the machine, including the clinching anvils, as well as the gripping mechanisms into proper widthwise and angular relation to the support 58 to adapt them for operating upon shoes of different shapes and sizes, a description of the adjusting mechanism will be left until after the fastening inserting mechanism has been described.

The fastening inserting mechanism comprises a stationary clinching anvil 255 at each side of the machine located beside the upper gripper I22 but positioned inwardly thereof, as viewed in Fig. 1, these anvils being so arranged with respect to a shoe on the support that they will clinch the fastenings just rearwardly of the tip line of the upper. As illustrated in Fig. 5, the anvil 2H for the right-hand mechanism is provided with clinching cavities 2 l 6 and has a cylindrical shank 2E8 mounted in a hole 226 formed at a proper angle in a relatively thick plate 222 interposed between the carrier member I26 and the supporting plate ltd, the plate 222 being fastened to the supporting plate by a screw 224 and a pin 228, and the anvilbeing adjustably secured in the plate 222 by a binding screw 228. As shown in Fig. 8, the opposite anvils 2 l 4 preferably extend inwardly slightly beyond the grippers H22 in order to locate the clinching cavities 2H5 in predetermined positions relatively to the edge of the bottom of the last in the shoe or, in other words, in definite lateral positions relatively to the angle or crease formed in the upper where its marginal portion is bent outwardly to overlie the projecting margin of the sole member, as shown in Figs. 9 to 11. The position of the fastening member or staple which is to be inserted in the upper at the opposite sides of the shoe, just rearwardly of the tip line, is rather critical and, accordingly, the anvils 2M have been made adjustable in the plates 22?. so that they may be varied as may be necessary to insure the correct positioning of the staples widthwise of the shoe, As illustrated in Figs. 11 and 13, the staples are located in the upper relatively close to the angle or crease formed by the outturned flange or margin of the upper but are nevertheless spaced from this crease a sufficient distance to permit the permanent lasting stitches to be inserted inwardly of the staples in the stitchdown lasting operation. The fastenings or staples utilized in the present machine are the usual type of preformed wire staples having two parallel legs joined by a bar portion, one of these staples being shown inserted and clinched in Fig. 12. The machine is arranged to receive the preformed staples from the well-known staple strips in which the staples are secured together in side by side relation by adhesive or otherwise to produce a long U-shaped bar or strip which may be, inserted bodily in a staple magazine provided in the machine and fed as a unit toward driving, position where the staples are broken off the strip one by one by the driving mechanism and inserted in the ,work piece. As illustrated in Figs. 1, and 7, the magazine for holding the staple strip comprises a pair of long, L-shaped side plates 236 spaced from each other by a bar member 232 and inclined downwardly at a small angle to the horizontal from their inner to their outer ends, the assembly being supported near its outer portion, a short distance forwardly of the plate I30, by a yielding pivotal connection 3M which will be described hereinafter. The L-shaped side plates 23%) and bar member 232 form the body portion of the magazine (Figs. 5 and '7), the side plates being secured to the bar by pins or rivets 234 located at spaced intervals along the members. The bar 232 is reduced in width at its lower portion 236, as shown in Fig. '7, to provide an opening or guideway 23'! in the magazine for receiving the staple strips which are inserted in an inverted position or with their legs extending upwardly, the strip being indicated in Fig. 5 by the numeral 238. Mounted for sliding movement in the space or guideway 23? is an elongated U-shaped staple feeding member 240, the forward or left-hand end of which, as viewed in Fig. 5, engages the outer end of the staple strip 236. The U-shapcd feeding member 223, as shown in Fig. '7, fits the ing member being provided with a downward projection or fin 242 which enters a vertical slot 2% extending lengthwise of a U-shaped block 246, the projection 262 being notched on its rearward edge to engage a pin 2&8 carried by the block. Mounted in the inner or forward end of the block 226 is a transverse pin 25% to which is secured the outer or free end of a long, coiled spring 252 composed of flexible material such as spring steel in the form of a ribbon, the inner end 254 of the spring being inserted into a transverse slot 255 extending through a short horizontal shaft 2556 (Figs. 5 and 6). The spring 252 is wound around the shaft 256 with a sufficient number of turns or coils 258 to cause the spring to exert enough tension on the block 2 36 to urge it constantly inwardly of the magazine and, through the feeding member 246, to feed the staple strip 238 inwardly toward the fastening inserting mechanism.

Fastened to the bottom of the U-shaped block 266 is a thin plate or strap 266 having a rearwardly extending end portion 252 which is bent downwardly at its outer end to provide a hook 262 which the operator may engage with his finger to withdraw the fee-ding member 266 when loading the magazine with a staple strip, this outer portion 262 also carrying another hook 266 positioned inwardly of the hook 266 which may be used if the outer hook happens to be located in an inconvenient position.

The shaft 256 supporting the coiled spring 252 is rotatably mounted in a housing or casing provided by a pair of vertical side plates 210, 212 (Figs. 1, 5 and 6) secured by screws 274 to the inner end of the bar 232 of the magazine, this casing also enclosing the spring and the staple insertin mechanism of the machine. As shown in Fig. 6, the shaft 256 has a slotted head 214 by which it may be turned in the casing to adjust the tension of the coiled spring and it has fiattened sid portions just rearwardly of the head whereby it may be held in adjusted position by a retaining plat 226 (Figs. 1 and 6) having a slotted upper end for engaging the flattened sides of the shaft, the retaining plate being fastened to the side plate 270 by a screw 218.

The inner edge of the rear plate 272, as viewed in Figs. 5 and 6, has a forwardly projecting wall 286 thereon which closes this end of the casing and, to the right of this wall, the plate has a relatively thick portion provided with a circular depression 282 for confining the coiled spring, the thinner front plate 276 fitting against this thick portion and the bar member 232 to close the forward side of the casing, as shown in Figs. 1, 5 and 6.

Pivoted on a horizontal pin 284 mounted in the side plates 22%, 272 is a downwardly extending link 266 the lower end of which is pivotally connected by a pin 238 between ears on the outer end of a substantially horizontal link 2516. The inner end of the link 296 is bifurcated to form ears and has pivotally connected between said ears by a pin 292 a driver bar 294 which is substantially rectangular in cross-section and projects upwardly into a slot or guideway 296 extending heightwise of the inner portion of the rear plate 2'12, the driver bar having a sliding fit in the guideway and the guideway being eniaiged in width inwardly of the driver bar, as shown at 298 in Fig. 6. Rigidly secured by rivets to the inner surface of the driver bar 294 is a driver 366 which has a sliding fit widthwise in the enlarged portion 298 of the guideway and is only slightly greater in thickness than the staples to be driven, the upper end of the driver 333 extending a substantial distance above the driver bar 234, as shown in Fig. 5, and its lower end being located in a slot 239 formed in .the enlarged lower portion of the driver bar.

The enlarged inner portion 238 of the slot or guideway 233 is closed to provide a closed passageway S ll for the driver and staples by an elongated throat piece 332 which fits into the enlarged slot and is securedin place by pins or screws 333. The upper portion of the throat piece is cut away opposite the driver 333 to provide clearance for the staples by a vertical slot 333. Secured in the slot 333 by a rivet 333 is a leaf spring M3 which projects upwardly and outwardly and bears against the upper end of the back or outer wall of the passageway 33!. The leaf spring 3E3 acts to prevent the bar portions of the staples, which are unsupported at their inner sides because of the clearance slot from bending or buckling inwardly toward the throat piece under the force of the driver when the legs of the staples meet the resistance or" the Work piece or of the clinching anvil. The spring 3W bears against the bar portion of the staple as it is entering the work piece and helps to maintain the staple flat in the passageway until it has been fully inserted into the work, the spring, of course, being deflected by the staple and driver 333 as they pass the spring, as illustrated in Fig. 11. As shown in Fig. 5, the upper end of the throat piece 332 and the adjacent portions of the side plate 2'12 which enclose the throat piec are beveled downwardly at a substantial angle, as indicated by the numeral 3I2, to provide clearance and to adapt the stapling mechanism for properly engaging the work piece or shoe.

Returning now to the yielding pivotal connection 35 3 referred to above for supporting the outer end of the staple magazine 233, the bar member 232 of the magazine, as illustrated in Fig. 1, is pivotally connected near its outer end by the pin 3E4 between a pair of cars formed on the lower end of a cylindrical sleeve member 3E6, shown in section at the left-hand side of Fig. 1, the sleeve member SIS being rotatably mounted in a hole formed in a rectangular'housing 3i3 projecting forwardly from the outer end of the supporting plate I33, the housing being preferably integral with the plate I30 and being inclined at an inward angle so that the sleeve member 3lt will be substantially perpendicular to the magazine when the latter is in its operative position. The sleeve member 3E3 is also slidable heightwise of the housing 313 and the opening or hole therein is reduced in size at its lower end and is threaded to receive a threaded rod which extends upwardly through the sleeve is surrounded by a spring 322. The upper end of the spring 322 engages an adjustable collar threaded into the upper end of the hole in the housing 3E3 and provided with a hexagonal head for turning it in the housing. The rod extends upwardly through the col- 13.1 has a pair of lock nuts 326 threaded on its upper end which engage the collar 323 retain the rod and sleeve 3E3 in the housing the tension of the spring 322 being determined or varied by the adjustable collar 323.

the pivot 3M, and also to swing laterally or widthwise of the support about the axis of the sleeve 333, the connection being yieldable heightwise, if necessary, by reason of the spring 322, although normally maintaining the magazine in its lowermost position, as shown in Fig. 1.

The intermediate portion of the magazine 23!], as viewed in Figs. 1 and 5, is supported by a roll 328 rotatably mounted on the rearward side of the bar member 232 on a pin 330 and extending into a cam slot 332 formed in the curved upper portion of an arm 3% of a large, three-armed rotatable lever 333 fulcrumed on a fixed stud 338 (Figs. 1 and 3) secured to the plate I33 by a nut 340 on its rearward end, the lever 333 having an inwardly extending arm 3G2 and an outer arm 3%, as best shown in Fig. 1. The fixed stud 338 extends some distance forwardly of the rotatable lever 33B and has pivotally mounted thereon an arm or lever 346 which extends inwardly toward the shoe support and has a rounded inner end 338 located directly below the driver bar 234 and in position to engage this bar and the connecting link 293 to operate the driver 333. This actuating or driving lever 345 has an outwardly projecting arm 35! which is much shorter than the lever itself and is normally engaged by a stop screw 332 threaded through a projection or lug 354 secured to the forward surface of the rotatable lever 335, this short arm 353 determining the inner or inoperative position of the rotatable lever when the mechanism is in its idle position, as shown in Fig. 1.

Mounted on the stud 333, in front of the driving lever 346, is a relatively heavy torsion spring 353 retained thereon by a washer 358 and a screw 35!] and having its rearward end portion extending outwardly relatively to the support 58 and engaging a screw 362 threaded into the lever 336. The forward end 363 of the torsion spring 356 extends inwardly and engages a screw 366 secured in the driving lever 346 so that, when under tension, the spring 353 tends to swing the driving lever upwardly about the pivot 333 and to rotate the lever 333 inwardly about its fulcrum toward the center of the machine or in a counterclockwise direction, as viewed in Fig. 1, with respect to the right-hand mechanism of the machine. Consequently, the spring 356 tends normally to maintain the rotatable lever 336 in a position in which the roll 328 on the magazine 233 is located at the outer end of the cam slot 332, and it simultaneously urges the driving lever 333 upwardly in a direction to operate the driver bar, the driving lever, however, being normally retained in its lower or inoperative position by a latch 368 (Fig. 1) pivotally mounted on the plate I33 by a pin are and having a downwardly inclined arm which is notched to engage a small rectangular block 372 rigidly secured to the rearward side of the driving lever 3 16.

As shown in Fig. 1, the latch 333 of the righthand mechanism of the machine is urged in a clockwise direction about the pivot 31% by a tension spring 314 secured to a pin on the latch and to another pin on the plate I33, the latch also having a short arm 316 extending from its upper end outwardly or toward the right. When the mechanism of the machine is at rest, as illustrated in Fig. 1, the latch 338 is in engagement with the fixed block 3'52 on the driving lever 343 and holds this lever against upward swinging movement under the action of the torsion spring 358. Since the driving lever is latched in a stationary position at this time, its outer arm 35%] serves as a stop or abutment against which the screw 352 will be held through the force of the spring 356 acting upon the rotatable lever 336, this position being such, as stated, that the roll 328 on the magazine 236 will be located at th outer end of the cam slot 332 in said lever.

The outer arm 3% of the lever 336 has a rod 380 pivotally connected to it by a screw 318, the rod extending downwardly and being loosely connected by a pivoted or rotary block member 382 to a forwardly extending arm or lever 384 (Figs. 1, 2 and 3). The lever 3% is fulcrumed at its rearward end on a long horizontal shaft 386 extending widthwise of the machine and rtatably supported in a pair of arms 38%, 399 which extend downwardly from a horizontal bracket 392 (Fig. 2) secured by bolts 395 to the lower surface of the plate or table 24 at the rear portion thereof, the shaft 385 being held against axial movement in the arms 338, 3% by collars 396, 398 secured to the shaft by set screws at opposite sides of the arm 388.

The lever 384 is fastened to the shaft 386 by a tapered pin dill] and has rigidly secured to its upper side by screws 482 a long, forwardly extending arm 104 (Figs. 1 and 3) provided at its front end with a handle 466 which may be grasped by the operator, the construction at the opposite side of the machine being substantially the same, as shown in Fig. 1, so that two handles 405 are provided at opposite ends of the long horizontal shaft 386, for swinging the levers 384 about the axis of the shaft, thereby preventing undue torsional strain on the shaft such as might result if only one handle were provided for operating the levers 384 pinned to the opposite ends of the shaft.

As indicated above, the type of shoe upon which the present machine is particularly adapted to operate is a stitchdown shoe, such as that illustrated in Figs. 8 to 13, inclusive, the illustrated shoe comprising at this stage of its construction an upper A, usually composed of a leather outer layer and a fabric inner layer or lining, the upper being mounted on a last C together with a leather sole member B which is temporarily secured to the'last bottom in the usual manner by tacks or other fastening means. The sole member B may constitute the insole o1 the finished shoe, or, in a three-sole stitchdown construction, the midsole of the shoe. The marginal portion of the upper A is bent outwardly to provide an outturned margin or flange F, as shown-in Figs. 10 and 11, and the marginal portion of the sole member B projects outwardly beyond the periphery of the last bottom to provide the usual sole extension or extension edge E of the sole portion of the stitchdcwn shoe. The staples which are separated from the staple strips 238 in the stapling mechanisms of the machine and are inserted in the shoe at opposite sides of the last are indicated in Figs. 11 to 13 by the letter S. As shown in these figures, the staples S are inserted at predetermined distances away from the angle or crease formed by the side of the last and the ou'tturned margin F. of the upper A and the staples are preferably located opposite or just rearwardly of the tip line of the upper. The upwardly projecting legs of the staples are clinched inwardly toward each other against the upper or exposed surface of the outer layer of the upper by the anvils 2M, and the staples are positioned by the fastening-inserting mechanisms so that their bar portions and the clinched leys will lie substantially parallel to the periphery of the last bottom or, in other words, to the edge face of the sole member B.

The handles ied on the arms 4% for operating the levers 384 on the shaft are depressed by the operator to cause the staples to be inserted and clinched in each side of the stitchdown shoe and thus to complete the operation of the machine on the shoe. These handles are not depressed, however, until after the gripping mechanisms have been operated by the treadle iilii and automatically locked in operated position, and also until after the shoe support 58 has been actuated by the treadle id to effect the relative movement which accomplishes the pulling-over operation, as described above, the treadle i l being likewise latched automatically in operated position. When the gripping and pulling-over operations have been performed, however, the arms or levers 355 3 are depressed to lower the levers at opposite sides of the machine and to pull down on the outer arms 34 2' of the rotatable levers 336 to swing the latter levers downwardly about their fulcrums 338 and to rotate the upper arms 3% outwardly, thereby moving the cam slots E32 outwardly. As shown, the cam slot in each of the arms 33 i is shaped so that its outer portion curves upwardly away from the fulcrum and its inner portion is concentric with said fulcrum. Accordingly, during the first part of the outward swinging movement of the lever 33%, the roll 328 is moved upwardly by the cam slot and, during the remainder of the swinging movement, the roll is maintained in its elevated position due to the concentric portion of the cam slot. Upward movement of the roll swings the staple magazine upwardly about the yieldable pivot Si l and moves the fastemng inserting mechanism carried by said magazine into operative position relatively to the shoe, as indicated in broken lines in Fig. 10, with the throat piece 362 pressing against the under side of the projecting sole member l3. Since the outturned margin F of the upper is at this time engaged by the grippers and also by the anvil 2M, it will be clear that, when the throat piece presses upwardly against the sole member, these outwardly extending portions of the upper and sole member become clamped firmly between the fastening inserting mechanism and the stationary anvil 2M. The staple magazine remains in its elevated position during the rest of the swinging movement of the lever during which time the fastening or staple S is driven and clinched against the upper.

Before the staple is driven, however, it is desirable to release the grippers i222, M4 at opposite sides of the shoe from gripping relation with the outturned margin F of the upper A because the upper margin and projecting portion E of the sole member are now clamped firmly between the anvil ili i and the throat member 362, as shown in Figs. 10 and 11. Release of the grippers takes place automatically shortly after the staple inserting mechanism has been swung upwardly to engage and clamp the projecting sole member and upper margin between the throat piece and the anvil, the lower gripper Hi4 being indicated by broken lines in Fig. 10 in the position it assumes after it has been released.

It will also be seen from an inspection of Figs. 9 and 10, that a substantial portion of the outturned margin F of the upper has been permitted to slip through the closed grippers I22, I44, this slipping action taking place during the pullingover operation on the shoe or, in other words, while the shoe support 58 was being moved upwardly and forwardly, as described above. This upward and forward movement of the shoe support is shown diagrammatically in Fig. 9 by indicating the initial or lower position of the support and shoe in broken lines and by illustrating in full lines a higher position where the support and shoe are being moved upwardly, this latter position being at a point in the pullingover operation substantially at the beginning of the pulling or tensioning of the upper over the last C. Fig. 10 shows the gripping mechanism after the pulling-over operation has been completed or at a point in the cycle of operations of the machine where the shoe support has moved heightwise its full distance so thatthe projecting margin E of the sole member B is located about opposite the tooth I46 on the lower gripper I44. It can be seen from these two figures that the outturned margin F of the upper has slipped or pulled through the grippers an appreciable amount under the tension of the pulling-over operation. The interlocking or toothed construction of the grippers I22, I44 is provided for the purpose of permitting this slipping action, this mechanism operating to grip and hold the upper margin with suflicient tension to produce a good pulling-over operation while, at the same time, permitting the upper to slip or pull through the grippers when the pull or tension on the upper exceeds a predetermined amount, as it usually does before the operation is completed.

The automatic release of the grippers I22, I44

is accomplished at the proper time in the operation of the machine by throwing out the latch I98 at the left-hand side of the machine which holds the rod I90 in its lowermost position and link 401 having an elongated slot 409 in its lower portion in which is located a rearwardly projecting portion 4 of the pin or screw 318, this rearward portion 4 being supported by a rigid arm 4I3 secured by screws to the rear side of the rotatable lever 336. When the lever 336 is swung downwardly by depression of the levers 404, the pin 4 moves down in the slot 409 and engages the bottom of the slot to lower the link 401 which, through the mechanism described above, swings the latch I98 inwardly or counterclockwise and releases the rod I90 for upward movement into its initial position. Since the rod I90 engages the block on the arm I86 which, in turn, is pinned to the rotatable shaft 46, it will be clear that release of the rod I90 also releases the shaft 46 for rotation which is then effected by the spring I80 to elevate the treadle I66 against the stop screw I82 and to raise the rod I90 and opposite rod I64, thereby breaking both gripper toggles I52, I56 simultaneously and causing the lower grippers I44 to swing downwardly into the open position shown in Fig. 1, and indicated in broken lines in Fig. 10. The latch I98 will be maintained bearing against the pin I62 by the spring 2I0 after release of the latch so that the against a cylindrical plunger latter will be in position to snap over the pin I62 and latch the rod I down again the next time it is depressed.

As the lever 336 of each unit is swung downwardly by the hand levers 404, the torsion spring 356 is wound tighter, thereby putting greater tension on the driving lever 346. At the same time, the inner arm 342 of the lever 336 is swung upwardly and, at the proper moment, engages the projection 316 on the latch 368 and wings the latch outwardly away from the block 312 on the driving lever, thereby permitting this lever to snap upwardly under the force of the torsion spring to strike the link 290 and driver bar 294 and operate the driver 300. The driver moves upwardly in its passageway to separate the innermost staple S from the staple strip 238 and to drive the staple upwardl with considerable force through the guideway and into the work piece, the staple, as illustrated in Figs. 11 and 12, entering the bottom surface of the projecting sole member B and passing upwardly through it and the outturned margin of the upper, and being clinched against the upper or exposed surface of said margin by the anvil 2 I 4.

The stapling mechanisms, including the magazines 230 and the staple inserting means, are returned to inoperative position automatically by a tension spring 420 (Fig. 2) attached at its forward end to a pin in the frame 20 and, at its rearward end, to another pin in the lower end of an arm 422 fastened by a tapered pin 424 to the shaft 386 to which the hand levers 494 are attached. When the hand levers are released by the operator and permitted to rise, after the fastenings have been inserted, the spring 420 pulls the arm 422 forwardly to rotate the shaft 386 in a clockwise direction, as viewed in Fig. 2, and thereby to elevate the arms 384 and rods 380 to move the staple'magazines and inserting mechanisms into the inoperative position they occupy in Fig. 1 bv the inward movement of the rotatable levers 339.

It w ll be noted, however. that while the levers 346 which actuate the driver bars and drivers are returned pos tively to imperative position by the st p screws 2 on the outer arms 334 of the levers 336, and also while they become latched down aga n automatically b the latches 368, the drivers and driver bars themselves are separate from these actuating mechan sms and therefore are not retracted by the positive return of the levers 336 to inoperative position. The driver bar 294 and driver 300 of each stapling mechanism are returned to inoperative position by a compression spring 426 (Figs. 5 and 6) mounted in a hole formed in a long, square block or bar 428 rigidly secured in an upright position to the rearward side of the casing plate 212 adjacent to the inner end of the staple magazine. As best shown in Fig. 5, the upper end of the spring 426 engages the closed end of the hole and its lower end bears 430 slidably mounted in the hole and engag ng a pin 432 project ng rearwardly from the link 296, the pin extending into a slot 434 formed near the lower end of the bar member 428 so that the pin can move heightwise relatively to the bar 428. When the driving lever 346 is retracted the spring 426 automatically returns the driver bar and driver to their inoperative position which is determined by the pin 432 engaging the lower end of the slot 434 in the bar 428, as shown in Fig. 5.

' i As stated above, the illustrated machine is provided with mechanism for initially adjusting the supporting plates I33 to vary the positions of the operating mechanisms carried thereby, including the grippers, fastening inserting means and anvils, relatively to the shoe support 58 in order to adapt'these mechanisms for operating upon shoes of diiferent shapes, styles or sizes, or, in other words, to locate these mechanisms at the proper positions and angles for operating on the opposite sides of the foreparts of the difierent shoes. In addition to the adjusting mechanism referred to, the machine is also provided with further mechanism for moving the supporting plates I38 inwardly toward the shoe shortly before'the insertion of the staples to cause the anvils 2I4 and'stapling mechanisms to move inwardly' relatively to the shoe with a yielding action to press the upper firmly into the angle or crease between the last and the projecting margin of the sole'and thereby to cause the upper to be" positioned as tightly as possible around the forepart of the last and also to locate the staples in the desired widthwise position with respect to the upper while so held, this inward movement of the mechanism taking place after the throat piece 382 has been swung upwardly into engagement with the sole member to grip it and the upper firmly between said throat piece and the anvil, as illustrated in Fig. 11. Referring to Figs. 2 and 3. the table 24 has rigidly secured to its rear portion by screws 436 a 'bracket 438 comprising a wide vertical 'plate 44fl extending transversely of the table and supported by two rear plates or ribs 442 to which the plate 448 is attached by screws 444 (Fig. 2). on th'forward surface of theplate 440 are provided'a pair of vertical projections or lugs 446 of substantial length towhichare pivotally secured by'pins'448 a pair of swinging carrier members 458-consisting of thick, vertical plates each of which has rearwardly projecting ears 452 located respectively at its upper and lower ends through whichthepin 448 passes.

At the front end of each swinging member 450 isprovided another pair of ears 454 which pro- =ject forwardly and between which is pivotally mounted by a pin 456 the plate I30 which carries the grippers, anvil and fastening inserting mechanism of the machine. It will be seen from the foregoing that each-supporting plate I 30 is movable-widthwise or laterally of the machine toward or away from the shoe support 58 by reason of the pivoted ca1rier'member'45U, and thateach plate I38 is also'rotatable relatively to the shoe support about the pivot 456 which 'connects the plate to the carrier member. This construction permits the plate I30 to be rotated into difi'erent angular positions with respect to theshoe support to locate the mechanism carried by the plate at the proper angle for operating upon the shoe on the support.

Secured by screws to the outer portion of each supporting plate I34 is an L-shapedbracket 458 which projects rearwardly and has pivotally'connected thereto by a pin 454 a link 462 which extends rearwardly over a cut-out portion in the bracket 44il'and is pivotally connected at its other end by a removable pin 444 to another L- shaped bracket 456 fastened to the plate 448, the connection at the rear end of the link being adjustable by reason of a series of holes 468 (Fig. 3) formed in the link into one of which the pin 464 may be inserted to connect the link in the desiredposition to the fixed bracket 466.

Securedto the outer side of each of the carrier members 454 is an elongated vertical plate or bar 410 the lower end of which is turned outwardly and has pivotally connected to it by a screw 412 a rod or eye-bolt 4% which extends outwardly substantially at right angles to the member 458 and, at its outer portion, passes slidingly through a block 414 (Figs. 3 and 4) rotatably mounted on the rearward end of a long horizontal lever 418 by a pin or shank 48E] integral with the block, the horizontal lever 418 extending forwardly of the machine in substantially the same'plane as the table 24, as shown in Figs. 1 and 3. A collar 482 is fastened by a set screw to the inner portion of the eye-bolt 414 and surrounding the bolt, between the collar and the rotary block 416, is a compression spring 484, the tension of which may be determined or adjusted by a pair of lock nuts threaded on the rod. 20

'The horizontal levers 413 at the opposite sides of the machine, which carry the rotary blocks 416, are normally parallel to each other and are pivoted about midway of their lengths on vertical pins488' secured by set'screws to a pair of swinging lever's or arms 4%!)[492 located respectively below the leftand right-hand levers 448, as viewedin'Fig'. 3, the arms 488, 492 being arranged for'swingina movement relatively to the levers 418, aswill be hereinafter explained. The horizontal levers4l8 extend forwardly of their pivots 488"and, at theirforward ends adjacent to the front of the machine, are provided respectively with rotatableblocks 494 mounted on the lower sides of the levers by 'means of integral pins or shanks 496 which are threaded at their upper ends to receive nuts 456 for securing the blocks to the levers. J

"Extending transversely across the front of the machine is a long horizontal shaft 544 rotatably mounted in a supporting block or hearing 542 attached by a stem or shank 594 to the lower sideof the table 24, the shaft 5ilil'being prevented from endwise movement in the block 582 by .a pair of'collars 585 secured to the shaft at opposite sides of the block by set screws. At its opposite end portions the shaft 580 is provided, respectively, with rightand left-hand threaded sections 508, 5 III which are threaded through holes in therotary blocks 494 on the levers 418; At its right-hand end, as viewed in Figs. 1 and 3, the shaft 580 is provided with a hand wheel 582 by which it may be rotated manually in the block 582 so that rotation of the shaft produces equal and opposite movement of the front ends of the levers 418 toward or away from each other. The shaft 500, therefore, provides manually operated means whereby the normally parallel horizontal levers'418 may be adjusted about their pivots 488 to swing their rearward ends equally and oppositely toward or away from each other. Such adjustment, through the yieldable connections provided by the rods 474 and springs 484 between the'levers 47B and the pivoted carrier members 458, causes the carrier members to swing about their pivots 448 in the lugs 445 the same amount and in the same direction as the rearward ends of the corresponding levers 418, no appreciable yield taking place in the connections at this time because there is nothing to obstruct the swinging movement of the members 45!. or to cause compression of the springs 484. i

Since the pivoted members 459 carry the supporting plates I34 at their forward ends. to which the latter are pivotally connected by the pins 456, it'will be clear that the plates I38 andthe operating instrumentalities carried thereby may be adjusted simultaneously equal amounts toward or away from the support 58 or a shoe mounted thereon in order to locate the operating mechanisms of the machine, that is, the grippers, anvils and fastening inserting mechanisms in the desired positions widthwise of the shoe. Moreover, as pointed out above. the angular positions of the supporting plates [39 relatively to a shoe on the support 58 may likewise be initially adjusted by reason of the manual adjustments provided by the removable pins Mid and the series of holes are in the links Q62, the plates its swinging about the forward pins 35 3 during the angular adjustment. After a shoe has been mounted and positioned upon the support 55, the operator adapts the opposite mechanisms for operating on that particular shoe by making the adjustments described above, the angular adjustment usually being made first and. the widthwise adjustment last in order to position the mechanisms accurately for operating upon the shoe. If the shoes to be operated upon are of the same general shape or style and do not vary greatly in size, the initial adjustments or" the operating mechanisms angularly and widthwise will in most cases be sufiicient for operating upon an entire lot of shoes.

The swinging arm 49 above referred to, which carries the pivot pin 588 for the left-hand horizontal lever l'lli, is fulcrumed on a vertical stud Ell (Figs. 3 and i) secured by a nut 5H5 to a stationary bar hi3 extending widthwise of the malchine below the Add and rigidly secured to the table 24 by bolts 52d. lhe opposite arm 492 is pivoted on a fixed stud. 522 fastened by a nut to the crossbar hi8. As illustrated. in Fig. 3, the swinging arm as; extends forwardly of its pivot 522 whereas the opposite arm Mill extends rearwardly from its pivot 5M. The arm dill! has a slot or opening 52 (Fig 4-.) formed therein in which is pivotally secured by a pin 526 a horizontal link 5223 which extends diagonally across the machine and is pivotally connected at its other end by a pin 53K! to the bifurcated forward end of the opposite swinging arm 4&2. Rotary or swinging movement of the left-hand arm 49! about its pivot 5H3, therefore, will, through the link impart to the right-h arm dill-l equal opposite direction.

The transverse shaft see at the rear of the machine, upon which the two arms 33 i and hand levers the are mounted, which is rotated by said hand levers to actuate the fastening inserting mechanisms of the machine, has rigidly secured to its righthand portion by a taper pin (Figs. 1 and 3) an upwardly extending arm to the upper end of which is pivotally connected in any usual a forwardly extendrod or link The front end of the rod is threaded into a connecting member 53-8 having ears which straddle the right-hand end of a relatively wide, horizontal lever Mil, the rod being pivotally connected to the lever by a pin 5 2 passing through said ears. The lever as illustrated Figs. 1, 2 and 3, extends transversely across the machine and is fulcrurned a little to the right of its central portion on a short vertical shaft 5% secured by a set screw 5 55 in a rectangular casting or block 5 rd fastened to the under side of the table 2 by bolts 53, the shaft 564 extending upwardly through the table 23, as shown in Fig. 2. The rectangular block 5 .8 is

slotted horizontally at 552 to support the central portion of the horizontal lever 54!! which, as shown in Figs. 3 and 4, extends toward the left and terminates below the swinging arm 490 in an enlarged, oval-shaped portion 554. The enlarged portion 554 of the lever has a cam slot 556 formed therein which, as illustrated, is substantially concentric with the fulcrum 544 of the lever 54!] at its opposite portions but curves sharply inwardly or toward the center of the machine at its intermediate portion. Positioned in this cam slot is a roll 558 rotatable upon a downwardly projecting pin 566 secured by a set screw in the rear end of the swinging arm 4%, as shown in Figs. 3 and 4.

In operation, the mechanism described above acts at the proper time in the sequence of operations of the machine to move the anvils 2M and the other operating mechanisms at opposite sides of the machine inwardly toward the shoe from their open or starting position, indicated by the broken line is. in Fig. 9, into their operated or position, illustrated by the broken line Y in Fig. 10. When the operator depresses the hand levers iflfi to cause the staple magazines and fastening inserting mechanisms to swing upwardly to grip the shoe upper between the anvils and throat pieces and also to release the grippers, described above, the arm 534 on the rear shaft 335 swings forwardly to rotate the cam lever ii lll about its pivot 54 5 in a clockwise direction, as viewed in Fig. 3, thereby swinging the opposite end of this lever and the cam slot rearwardly so that the roll 553 on the arm 5-30 is swung sharply inwardly or toward the right about its pivot 54 by the shape of the cam slot Inward movement of the swinging arm 554 causes a reverse or outward swinging movement, of the opposite arm dill! about its pivot 522 through the connecting link 52%.

As explained above, the swinging arms 490, carry the fixed pivots @253 about which the horizontal levers did fulcrum when they are adjusted manually by rotation of the oppositely threaded screw 588 to move the supporting plates E35! and the operating mechanisms toward or away from the shoe support 58 in order to position these rnech sins initially for operating upon the shoe. It .il be noted, moreover, that the two pivots 383 for the levers 5'8 (Fig. 3) are located rearwardly of the fillfllllms SM, 522 for the swinging arms 39%}, ii- 2 so that inward swinging movement of the left-hand see,

iever or outward movement of the righthand 5522. moves both pivots sea inwardly toward the center of the machine and toward the shoe support '53. This inward movement of the pivots 188 for the levers lls causes these levers to swing inwardly about fulcrum now provided by their pivotal connections to the oppositely threaded rod or screw 5% or, in other words, about the cent rs of the shanks 4&6 of the rotatable blocks The rearward ends of the levers d? 'e, automatically swung inwardly la;- is action and, through their yieldin: connections to the carrier members see provided b 'oe eye its and springs its, cause these lswing inwardly about reby to move the cppov ,r'lly toward the shoe, this yieldable because the levers H8 is transmitted or applied thr springs .54 surrounding the eye-bolts rthe operating mecharusms at each side of the machine have been in\ aid merit thus moved inwardly a predetermined distance to press the upper margin F tightly into the angle formed by the projecting sole member and the side of the last, the anvil and throat piece are caused to remain in such position, as illustrated in Figs. 10 and 11, while the staple is driven because of the concentric forward portion of the cam slot 555 in the horizontal lever 549.

Although the operation of the machine will be apparent from the foregoing description, a brief summary will be given here for the purpose of clearness. The operator mounts a stitchdown shoe on the support 58, the shoe preferably comprising the usual two-ply upper, such as the upper A, illustrated in Figs. 8 to 13, inclusive, the upper being assembled loosely on the last with a sole member B which is temporarily secured to the last bottom by tack or similar means. As shown in the figures referred to, the sole member B, which may constitute either the insole or the midsole of the finished shoe depending upon the type of stitchdown shoe to be made, projects beyond the edge of the last bottom in the usual manner to provide the sole extension or margin E to which the outturned margin F of the upper is to be attached when the upper is lasted.

The operator adjusts the toe gag I l and the side gages I85 as much as may be necessary for the size and shape of the shoe being operated upon, the toe gag M being adjusted, as explained above, by loosening the clamping screws '38 and threading the adjusting screw 88 into or out of the block '46. The side gages ISI may be adjusted or set widthwise by moving them in the slots 285 and then tightening the screws I83.

After positioning the gages properly for the shoe, the operator will adjust the opposite operating mechanisms of the machine into the proper widthwise positions relative y to the support 53, and he will also adjust them into the proper angular positions relatively to the opposite sides or edges of the forepart of the last in the shoe. It should be pointed out that the shoe support 58, as shown in Figs. 1, 2 and 11, is cut away at the portion opposite the operating mechanisms of the machine to permit these mechanisms to move inwardly far enough to come into operative engagement with the shoe.

In adjusting the operating mechanisms widthwise, as pointed out above, the operator turns the hand wheel 5I2 to rotate the screw 5G8 and thereby to swing the carrier members 459 and supporting plates I 35 toward or away from the shoe support through the movement of the horizontal levers 31 8 and the pivotal connections between them and the carrier members 459. In order to shift the operating mechanisms angularly with respect to the shoe, the operator merely removes the rear pins 364 from the links 462 and swings the supporting plates I38 into the angular positions which, in his judgment, are best suited for the shoe being operated upon, and then inserts each pin 464 in the proper hole 468 in the link to maintain the supporting plates in such angular positions.

After having made the necessary adjustments for the shoe being operated upon and thereby positioned the mechanisms properly not only for that shoe, but for an entire lot or run of shoes of substantially the same size and shape, the operator makes sure that the opposite marginal portions of the forepart of the shoe upper overlie .the grippers and are in position to be gripped thereby when the gripmrs are operated. The

operator then depresses the treadle I66 (Fig. 1) to straighten the toggles I52, I55 of the opposite gripping mechanisms which causes the lowor gripper jaw Hi l to swing upwardly and to grip the margin of the upper between it and the upper gripper I22, as illustrated in Fig. 9. The gripping mechanisms become locked automatically in operated positions by the latch 93 at the left-hand side of the machine, so that the operator may remove his foot from the treadle immediately and proceed with operating the rest of the mechanisms.

He next depresses the treadle 54 to cause the shoe support 58 to move upwardly and forwardly to perform the pulling-over operation on the shoe, this movement of the support being caused, as explained above, by elevation of the parallel arms 59, 52 (Fig. 2) through the straightening of the toggle 34, 36 while, at the same time, the parallel links as on the toggle are moved forwardly by movement of the rear link 35 to cause the arm 50 to swing forwardly and to move the shoe support in a forward direction, the support remaining horizontal throughout this movement because of the parallel arms. The operator usually holds the shoe steady on the support during this operation by placing his hand on the cone of the last and pressing the last lightly against the support to prevent accidental movement or displacement of the shoe. Fig. 9 illustrates somewhat diagrammatically the heightwise movement of the shoe support from its initial position to a point where the grippers are just beginning to put tension or pull on the upper although not, as yet, sufiicient tension to cause the upper to slip through the grippers as it will later in the pulling-over operation after the tension on the upper becomes greater. When the support 58 has completed its upward and forward movement, it becomes latched automatically in its operated position by the latches H34, I66 which drop under the pin 49 at the forward end of the toggle 34, 35 and thus hold the toggle in its straightened position.

If the upper has not been pulled over properly or has become twisted or displaced during this part of the pulling-over operation, the operator may, if he so desires, stop the operation before it has been completed and inspect the shoe without entirely releasing the mechanisms, this being possible, as explained above, because the latch I06 for locking the toggle 34, 38 is notched slightly lower than the opposite latch Ill i, which permits the operator to stop the machine while the mechanisms are held by the lower latch I06 in the positions they then occupy. If he should find that the shoe or upper has become displaced or was being pulled over unevenly, he can release the shoe support 58 by means of the handles H8, 528 on the latches I04, I and thus permit the toggle to break and the support to return to its initial or lower position. Furthermore, if it should become necessary to release the grippers in order to reposition the shoe or to straighten the upper before proceeding, the operator can also release the gripping mechanisms by means of the upstanding projection or handle ZIZ (Fig. 1) which disconnects the latch I98 and permits the gripper toggles to break and thereby permits the grippers to open and return to their inoperative positions. If an inspection indicates that the shoe is being held and pulled over properly,- the operator resumes the depression of the treadle M toward its final or lowermost position at which point the higher latch I04 (Fig. 2) drops under the pin 49 and locks the shoe support in its elevated position.

The shoe has now been pulled over the last and the forepart, back part and side portions of the upper have been pulled firmly against the last by the forward and upward movement of the shoe support relatively to the stationary gripping mechanisms. Moreover, the opposite margins of the upper held by the grippers have been permitted to slip through the grippers as much as was necessary to prevent tearing theupper while, at the same time, being held firmly enough to produce a good pulling-over action so that the upper will lie smooth and flat against the forepart of the last. The operator now grasps the opposite handles 4% and depresses the hand levers lfi l which cause the remaining operations of the machine to take place, these operations comprising first, the clamping of the upper margin F and the sole extension. E between the throat pieces 3&2 and anvils Ki l, secondly, the automatic release of the opposite gripping mechanisms, thirdly, the inward movement of the operating mechanisms toward the support to insure that the upper is positioned or pressed tightly against the last at the angle or crease adjacent to the last bottom, and, finally, the inserting or driving of the staples and clinching of them against the upper surface of the outturned margin of the upper.

As explained above, as the hand levers 464 are moved downwardly, the rotatable levers 333 at opposite sides of the machine swing outwardly to elevate the rolls 328 in the cam slots 332 of the upper arms 33% of the rotatable levers. Upward movement of these rolls causes the staple magazines to swing upwardly about their yieldable pivots 314 toward the position shown in Fig. 11, where they will engage the sole extension E and grip it and the margin F between the throat pieces 3&2 and the anvils 2E4. Before this upward movement is completed, however, but after the throat pieces have moved into gripping relation with the sole and upper, the latch I98 (Fig. 1) for the grippers is automatically released by the pin MI engaging the bottom of the slot 409 in the link All! and pulling downwardly on the member 205 to swing the latch inwardly and release it from engagement with the pin I62.

After the upper margin and projecting sole member have been tightly clamped between the throat piece and the anvil 2 i 4, and after the gripgers have been released, the mechanisms are retained in this clamping relation until after the staples have been driven, due to the shape of the inner portions of the cam slots 332, which are concentric with the axes of the studs 338 about which the levers 336 rotate. Accordingly, the upper and sole member will remain clamped until they are secured in this position by the fastening means or staples. As the hand levers 464 are depressed toward their lowermost positions, the rotation of the shaft 386 to which they are pinned swings the arm 534 forwardly and, through the connection 536, causes the horizontal cam lever 540 to be swung in a clockwise direction, as viewed in Fig. 3, about the pivot 544 to move the lefthand end of this lever and the cam slot 556 rearwardly, thereby swinging the arm 499 inwardly about the fixed pivot 5M. This movement of the arm 496 swings the opposite arm G92 outwardly so that the central pivots 483 for the horizontal levers 418 are moved inwardly equal distances as determined by the cam slot The levers 578 are thus caused to swing about the forward pivots 496 on the adjusting screw so that their inner ends swing inwardly predetermined amounts. The yielding connections between the inner ends of the levers did and the carrier members 459, swing the carrier members inwardly about their vertical pivots and they he opposite plates I30 inwardly toward he she support with a yielding action provided by the springs The effect of this mechanism, therefo e, is to move each throat piece and each anvil 2%, which are now in gripping relation with the sole mem ber and upper, inwardly toward the support with a yielding action to the upper into closer engagement with the sides of the last, particularly the lower portion of the upper adjacent to the angle between the last and the sole margin or extension While this movement is usually relatively slight, it in some cases, be sunicient to be noticeable. lustration of this inward movement is indicated diagrammatically by the broken lines and Y in Figs. 9 and 11, respectively, the line X showing the position of the mechanism before the inward movement and the line Y showing its position after such move ment.

When the inward movement of the throat piece and anvil has taken final depression of the hand levers ite actuates the staple inserting mechanisms of the machine to compiete the operation upon the shoe, i driving of the staples, as pointed out above, bemg accomplished by up ward movement of the inner arms of the rotatable levers into engagement with the projections Eli? on the latches to release these latches from the lugs Eilii on the driving levers 3'36 and to permit the latter to operate, the torsion springs being wound tighter by the on ward movement of the levers so that tension or load on the driving levers is increased prior to the driving operation. Release of the latches 368 permits the driving levers to snap upwardly to operate the drivers and cause them to break off a staple S from the strips 233 and to insert in the clamped portions of the sole member and upper, as shown in Figs. 11 and 12, the staple S being clinched against the upper or exposed suriace of the margin F by the anvil 2%.

Figs. 11 to 13, inclusive, show th .t the staple S is driven parallel to the edge face of the sole member B and is clinched by the anvil so that the clinched portions of the legs are turned inwardly toward each other and lie parallel to the edge face of the sole. is illustrated in Fig. 13, the staples are located a relatively short distance outwardly from the crease or angle between the side of the upper and its out-t rned this distance being important because it desirable to have the staples locate-d su iently close to this crease to cons tute a satisuctcry pullingover operation win on the other they should also is from the side portion of the a sufiicient distance to permit the permanent stitches inserted in the stitchdown lasting op aticn to pass between the side of the up er and the stapl 1thout running into or striking the staples and either breaking the needle of the stitching machine, or severin or damaging the thread forming the stitches.

After the staples have been inserted and clinched in the shoe parts in the manner described, the operator releases the hand levers and permits them to return to their initial elevated positions by the spring 420 (Fig. 2) which, in turn, causes the levers 336 to swing inwardly to return the staple magazines and associated mechanisms to their Original or inoperative positions. Since the driver bars and drivers are separate from the driving levers 345, the drivers 350 do not return to inoperative position by reason of the return of the driving levers into their latched positions, as illustrated in Fig. l, and, consequently, the compression springs 426 (Fig. 5) function at this time to retract the drivers and driver bars to their lowermost positions below the staple strips 238, thereby permitting the staple strip to be fed forwardly into the driver passage under the action of the feeding member and coiled spring 252 and thus locate another staple in position for the next shoe to be operated upon.

After the staple magazines and associated mechanisms, including the driving levers and drivers, have been returned automatically to their inoperative positions, the shoe support 58 may be released from its elevated and forward position and caused to return to its initial lower position, as shown in Fig. 2, by tripping the latches H34, H16 manually by their handles H8, i211, to permit the treadle rod 42 to be raised by the spring 8 to break the toggle 34, 35 and cause it to assume the position shown in Fig. 2, this position being determined by the forward stop screw me on the toggle link 34. The operator may then remove the pulled-over stitchdown shoe from the support 53, mount the next shoe thereon, and repeat the operations described above, the adjustments of the toe and side gages and the operating mechanisms, however, being necessary only when the next shoe to be operated upon differs substantially in size and shape from the last shoe operated upon.

While the invention has been disclosed herein with reference to machines adapted for use in performing pulling-over operations upon shoes, and more particularly, in performing such operations upon stitchdown shoes, it is obvious that, in its broader aspects, the invention is not limited to such operation or to operating only upon stitchdown shoes, since many of its features and advantages could be employed with equally beneficial results in connection with other operations upon shoes, such operations, for example, as the assembling or lasting operations, and the invention or features thereof could also be utilized to advantage in connection with the manufacture of shoes other than stitchdown shoes.
